James, from Cottenham, Cambridge asked:
Who is sweatier, men or women ?
Men are definitely sweatier than women. Previously this was put down to the larger male stature, but a team of scientists at University of Dortmund, Germany, led by Barbara Griefahn, say different. In their laboratory they have set up a mock 'sweltering car'. 'Volunteers' sit for up to 2 hours under heat lamps, mimicking the effect of the sun beating down through the windscreen. Under these conditions men lose about 250 mls of sweat per hour during the experiment, 70 mls an hour more than female volunteers. This makes them officially sweatier, even allowing for size and weight, say the scientists.
